Bike Tire Pressure Support

Last Updated: 2026-10-23

Bike Tire Pressure is an offline bicycle tire-pressure calculator from TomatoPeter Studio. On the device it is named Tire Pressure. The app can use English or Simplified Chinese.

What you can do

  • Save up to 8 bikes, with a name, bike type, weight, tire and wheel measurements, casing, rim, and ride style.
  • Save up to 8 riders, with a name and weight.
  • Choose PSI, bar, or kPa, and kilograms or pounds.
  • Use the system language, English, or Simplified Chinese.
  • Select surface conditions and see a starting front and rear pressure on this device.

How to read the result

The pressure is estimated from the rider and bike weight, tire and rim measurements, casing, ride style, and surface conditions you enter. Use it as a starting point and adjust it before you ride. It is not a limit set by the tire or rim maker. Follow the pressure limits for your tire and rim.

What stays on this device

Bikes, riders, and settings are stored in a local file in the app. The App Store version does not require an account and does not include advertising, analytics, or in-app feedback. We cannot see that file.

The app does not offer cloud sync or an export. If a saved file cannot be read, the app may keep a copy of the original file in the same local folder before writing a new one. That copy is not a backup service, and deleting the app removes the local files. We cannot restore them.

Email questions about the app to [email protected]. Please do not expect the message to include your saved bikes or riders. We only see what you choose to write.

骑行胎压支持

最近更新：2026-10-23

Bike Tire Pressure 是 TomatoPeter Studio 的离线自行车胎压计算应用。设备上显示的名称是 Tire Pressure，中文界面为“骑行胎压”。应用可以使用英文或简体中文。

可以做什么

  • 最多保存 8 辆车，包括名称、车型、重量、轮胎和轮圈尺寸、胎体、轮圈和骑行风格。
  • 最多保存 8 位骑手，包括名称和体重。
  • 胎压单位可选 PSI、bar 或 kPa，重量单位可选千克或磅。
  • 语言可以跟随系统、使用英文或简体中文。
  • 选择路面状况后，在这台设备上查看前后轮的出发胎压。

如何理解结果

胎压根据你输入的骑手和车辆重量、轮胎和轮圈尺寸、胎体、骑行风格及路面状况估算。请把它当作骑行前调整的起点。它不是轮胎或轮圈厂家规定的限压。请遵守你的轮胎和轮圈的限压。

哪些内容留在这台设备上

车子、骑手和设置保存在应用的本地文件中。App Store 版本不需要账号，也不含广告、统计或应用内反馈。我们看不到这个文件。

应用不提供云同步或导出。如果已保存的文件无法读取，应用可能会先在同一本地文件夹保留原文件的一份副本，再写入新文件。这份副本不是备份服务。删除应用会移除本地文件，我们无法恢复。
